IMPROVEMENT IN ORGAN-ACTIONS.

Specification forming part of Letters Patent No. 211.169, dated January 7, 1879; application filed October 12, 1878.

To all whom Iit may concern:

Be it known that I, Crans E. LYON, of Worcester, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Organ-Actions; and I declare the following to be a description of my said invention sufficiently full, clear, and exact to enable others skilled in theart to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 is a part front, part sectional, view of a portion of an organ-action, illustrating the nature of my invention. Fig. 2 is a vcrtical section ofthe same at line fc, Fig. l.

One feature of my invention consists in providing the extended or chambered reed-cells in an organ-action with an upper or second se ries of openings or passages, in addition to the ordinary openings, and combining therewith a double set of mutes for closing said passages, as hereinafter described, whereby the power, quality, and variety of tone are enhanced and control thereof facilitated.

Another feature of my invention consists in the peculiar arrangement of the inclined lug and crank devices for operating the mutes, as hereinafter fully described.

The particular features claimed are hereinafter deiinitely specitied.

In the drawings, A. denotes the reed-board; B, thebrace-board, Bl, the naine-piece, through which are arranged the stop-pulls C, and D, the cell plate or board, which contains the reed-cells D1, and upon the face of which are arranged the mutes or stop-valves.

The cell plate or board D, make of somewhat greater thickness than in ordinary actions, and forni the reed-cells Dl with upward` extending chambers D?, and at the upper part of said chambers I form openings or auxiliary passages E to the exterior of the plate l) separa-te from and in addition. to the ordinary cell-opening F, which latter is retained in its customary position and form, thus givin gtwo sets of openings into the reed-cells Dl D2 for the passage of air into and exit of sound from said cells.

Separate mutes E and F1 are arranged over the two series of openings E and F, respectively, sail mutes being hinged to the front part of the cell-plate D, te swing upward for opening the passages, and are provided with suitable springs for closing them, in the ordinary inanner. Said mutes E F1 are, in the present instance, linked together for action by means of a bar, G, pi voted to short projecting arms c and j' on the respective mutes, so that when the mute Fl is raised the mute El will also be elevated by the same action. 1f preferred, however, a separate action or stop can be used for opening the mute E, and I design to employ such mutes both with separate and combined operating devices.

The mute Fl is raised by means of the connecting-bar H, the forward end of which is pivoted to the mute-arm F2, while its rear end, which is furnished with a loop or eye, 7L, (see dotted lines, Fig. 2,) is attached to the downwardly-projecting arm IZ of the crank shaft or rod lin such manner that it can be readily disconnected, when desired, by raising the loop 7L from the crank-pin at the end of said arm l?.

The crank-shaft I is supported in bearings l) b on the upper side of the bace-board B, with its actuating-crank Il projecting upward and forward in an inclined position, as indicated in Fig. 2, beneath the pull-bar O, where it is engaged and pressed downward with an easy and uniform rolling movement, when said pull-bar O is drawn, by means of the inclined surface of a lug or block, O', fixed to the lower side of the pull-bar C, as illustrated.

By arranging the crank-bars I .il on the brace-board E and the inclined lugs on the under side of the pulls, while said pulls are arranged through the name-piece 131 and rear support-piece, B2, a very simple and perfectly operating stop device is produced, while the said parts being so arranged upon the brace B Bl greatly facilitates the operation of putA ting the organs together, since the action proper can be adjusted to position first, and the brace B and parts connected therewith then put on as a whole and secured in place, simply requiring the looping on of the eyes hy to the arms l2 to complete the connection.

The inclined lug U', working against the crank il in inclined position, as shown, gives tion and direction of pressure is such that the action is prevented from pounding or striking back with a sharp blow when the pulls are pressed in. A wire, c, arranged to work in a groove inthe piece B2, serves to prevent the pull C from turning or revolving so as to carry the lug C out of place.

By forming upper openings in the reed-cells in the manner described, greater power is given to the reeds while the quality of tone is improved; and by the aid of the double set of mutes greater-variety of tone can be produced, while the action is under complete control.

I am aware that reed-cells have heretofore been provided with chambers for improving the tone of the reeds, vand I do not broadly claim chanibered reed-cells; neither do I claim, broadly,'an inclined surface or wedge for moving the mute-operating devices.

' What I claim as of my invention, and desire to secure by Letters Patent, is

-1. 'In combination with the reed-cell having opening F and mute F1, the upper opening or auxiliary passage, E, and mute El, substantially as and for the purposes set forth.

2. In a reed-organ action, the cell-board I), constructed substantially as hereinbefore de- Y scribed, with high-chambered reed-cells D1 D2,

havin g lower openings, F, and upper openings,

. E, provided with separate mutes F' and E', as

set forth.

3. In combination with the cell-board D, having reed-cells withtwo openings, the double mutes E F, connecting-link G, arm F2, connecting-bar H, crank-rod I, and pull G C', substantially as and for the purposes set forth.

4. The combination, substantially as shown and described, of the mute F1, having arm F2, the connecting-bar H, crank-shaft I, supported inV bearings b b on the brace-board B, with its crank end Il inclined upward and forward, and the pull-bar C, provided with an inclined lug, C1, at its lower side, for engaging said crank end and operating the part-s in the pef culiar manner set forth.

5. The combination, in an organ-action, of the brace-boards B B, the pull-bar C, arranged in relation thereto as shown, and provided at its lower side with an inclined lug, C', and thc operating crank-shaft I, supported in bearings b b on said brace-board, with its crank end inclined upward, as shown, whereby, when the stop or pull is drawn, said crank will be depressed with a uniform rolling motion, as hereinbefore set forth.

Witness my hand this 30th day of September, A. l). 1878.
